TEGUCIGALPA, Honduras 
The head of the Organization of American States closed the door Friday on a compromise offered by Honduras' interim leader because it would not restore the president ousted in a coup.

OAS Secretary-General Jose Miguel Insulza warned there will be no agreement to end Honduras' crisis unless Manuel Zelaya returns to the presidency.

The interim government "has not ceded on one of the principal points, which is the return of President Zelaya. And we are also not going to cede on that issue," Insulza said in an interview with Chile's La Tercera newspaper. "Therefore, until there is a consensus on that, there will be no agreement. Zelaya must return as president of Honduras."

Interim President Roberto Micheletti offered this week to resign if Zelaya gives up his claim to the presidency. Under the plan, a third party would be appointed to serve out the remainder of Zelaya's constitutional term, which ends in January.

Arturo Corrales, a negotiator for the interim government, said Micheletti presented the plan to a delegation of foreign ministers from the OAS in Tegucigalpa on Tuesday.

Corrales said Micheletti was also prepared to back a limited amnesty for Zelaya, who was charged with abuse of power and other counts and forced into exile in a June 28 military coup.

However, Micheletti appeared to withdraw his support for the amnesty Friday, insisting that Zelaya must be tried if he returns to Honduras.

"If need be, I will resign, as long as Zelaya does not return to the country. And if he comes ... let him come and face justice," Micheletti told Channel 10 television.

And late Friday, the interim government issued a statement saying it had sent Costa Rican President Oscar Arias – who has served as a mediator in talks on the dispute – yet another set of proposals.

The Foreign Ministry said the message included three proposed alternatives to Zelaya's return, but did not specify what they were.

At a news conference in Managua, Nicaragua, Zelaya also rejected any deal that doesn't include his reinstatement and said the scheduled election to replace him would not be legitimate otherwise.

Zelaya said his return as president is a "condition sine qua non for a transparent and democratic electoral process." He said the interim government was seeking to use the Nov. 29 presidential election to "legitimize the coup."

About 1,000 Zelaya supporters, meanwhile, marched in a poor neighborhood of the Honduran capital, Tegucigalpa, to demand his return to power and mark two months since the coup.

Despite worldwide condemnation of the coup, Micheletti insists Zelaya was legally removed from office by the Honduran Congress for defying a Supreme Court order to drop efforts to change the constitution.

U.S. State Department spokesman Ian Kelly said Friday that Washington continues to support a compromise proposed by Arias that would restore Zelaya with limited powers and require him to abandon ambitions to change the constitution.

Critics of Zelaya say he was planning to extend his time in office by removing a ban on presidential re-election. Zelaya denies he was seeking to extend his term. He says he supports the Arias plan, but Micheletti has rejected it.
